  • Fluoropolymer compositions and purification methods thereof
    Patent number: 9809658
    Abstract: Described herein is a method of purifying a product and recycling water comprising the following steps: (i) providing a crude product comprising at least one low molecular weight fluoroorganic compounds wherein the low molecular weight fluoroorganic compounds is partially fluorinated and comprises a polar group and/or a reactive group; (ii) extracting the impurity from the product using water to form an extract, (iii) contacting the extract with a radical-forming process to degrade the low molecular weight fluoroorganic compounds into carbon dioxide, water, fluorine ions, and optionally cations; and (iv) using the water from step (iii) in step (ii)

  • Fluoropolymer compositions and purification methods thereof
    Patent number: 9453086
    Abstract: Described herein is a composition comprising an aqueous polymerization reaction product of fluorinated monomers and wherein the polymerization is initiated (i) in the absence of a fluorinated emulsifier and whereby no fluorinated emulsifier is added during polymerization or (ii) in the presence of an fluorinated emulsifier selected from: [Rf—O-L-COO-]i Xi+ (I) wherein L represents a linear or branched, non-fluorinated, partially fluorinated, or fully fluorinated alkylene group, Rf represents a linear or branched partially or fully fluorinated aliphatic group or a linear or branched partially or fully fluorinated aliphatic group interrupted with at least one oxygen atom, Xi+ represents a cation having the valence i and i is 1, 2 or 3; wherein the reaction product and/or the resulting aqueous phase are substantially free of di- and tri-alkylamines and substantially free of low molecular weight fluoroorganic compounds and methods thereof.
